| Oct 31, 2018 at 16:36 | comment | added | Harper - Reinstate Monica | Or make that 4-way intersection a 5-way. Lots of ways to buy some run length. | |
| Oct 31, 2018 at 16:14 | comment | added | ratchet freak | @aitchnyu You then have the same problem over half the distance because you need to clear the road you went over as well. And you have to disown and demolish half a dozen properties. | |
| Oct 31, 2018 at 16:11 | comment | added | Jesvin Jose | I was thinking this imgur.com/a/9v6B9UT The current road will have to be diverted to meet the bridge end | |
| Oct 31, 2018 at 15:24 | comment | added | yo' | I believe @aitchnyu meant, when going North, having a right turn uphill parallel to the railway followed by a left turn over the railway and finally a slight right turn on the other side to align and quit on the north-east. However, this would not add much available slope length when considering possible widening of the railway. | |
| Oct 31, 2018 at 14:13 | comment | added | Forward Ed | Rachet is saying you need the extra length of road to get to the height required to pass over top rail tracks safely. A tighter loop probably could have been used, but it looks like they are circling a storm water management pond or the like. | |
| Oct 31, 2018 at 12:10 | comment | added | ratchet freak | @aitchnyu extended to where? because that would not physically fit, which would result in either the trains crashing into the span or a lip at the intersection. | |

| Oct 31, 2018 at 11:29 | comment | added | Solar Mike | And to probably help reduce the speed of approach to the junction... | |
